Benefits of technology

The patent describes a technology that uses an ultracapacitor to charge a dynamic transaction card. This type of device provides higher energy density, fast charging and discharging, low heating, safety, and stability. The ultracapacitor is integrated onto a printed circuit board (PCB) which allows it to be charged via insertion into EMV terminals for payment. The technology also utilizes a printed circuit board to save on PCB height. Overall, this technology offers an improved solution for energy storage in dynamic transaction cards.

Problems solved by technology

The power source utilized to power smaller electronics may dictate the size and shape of the devices, and may often result in long charge times and / or provide relatively slow power delivery.
However, batteries often consume a large percentage of space in smaller electronic devices, which poses design limitations where a device must be a particular size or shape for user or compatibility purposes (e.g., to fit in the palm of a user's hand, to be compatible with a machine that receives the device, etc.).
This current design also requires the use of complicated smart card power management topology.

Embodiment Construction

[0037]The following description is intended to convey a thorough understanding of the embodiments described by providing a number of specific example embodiments and details involving a PCB with a power source and methods for manufacturing a PCB with a power source, to enable a dynamic transaction card to draw the power it needs to communicate with a smartphone via insertion into EMV terminals for payment. The associated system may harvest energy from an EMV terminal to charge or recharge a dynamic transaction card when the card is inserted into a terminal. It should be appreciated, however, that the present disclosure is not limited to these specific embodiments and details, which are examples only. It is further understood that one possessing ordinary skill in the art, in light of known systems and methods, would appreciate the use of the invention for its intended purposes and benefits in any number of alternative embodiments, depending on specific design and other needs. A dynam...

Abstract

A printed circuit board (“PCB”) with a power source. The PCB and power source combination may be inserted into a small electronic device, such as a dynamic transaction card, which may include a dynamic transaction card or a EuroPay-MasterCard-Visa (“EMV”) card. For example, a PCB may be manufactured to attach a battery as a power source to one side of a PCB such that the integrated battery directly connects with at least a portion of the PCB side. A rapid energy storage device may also be utilized as a power source. Energy may be harvested from an EMV terminal to charge or recharge a dynamic transaction card or EMV card powered by a rapid energy storage device when the card is inserted into the terminal.
